Letters Patent No. 101,693, dated April 5, 1870.

' IMPROVEMENT IN SNOW-PLOWS FOR RAILWAYS.

The Schedule referred to in these Letters Patent and making part, of the same To all whom it may concern:

Be it known that I, ROBERT WrLsos, of Des Moines, in the county of Polk and in the State of Iowa, have invented certain new and useful Improvements in Snow-Plows for Railroad-Oars; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying' drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a snow-plow for railroad'cars, as will be hereinafter fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and uset-he same, I- will now proceed to describe its construction and operation, referring to the annexed drawing, in which-- Figure 1 is a side elevation, and

Figure 2, a plan view of my machine.

Figure 3 is a. bottom View of the front end of the same.

A A represent two of the usual railroad trucks, upon which is placed a car, I5, having its upper side inclined upward from front to rear, and also slightly downward from the center toward each side.

To the front end of the car B is pivoted or coupled another car, 0, resting upon a smaller truck, D, and

so constructed that its upper surface will continue the inclination of the car 13, both sideways and also toward the front, the front edge being steel shod, and placed at such a height as to be immediately above the upper surface of the rails.

The steel edge a, at the front end of the car 0, acts as a cutter 0r scraper to loosen the snow from the rails.

- the snow from collecting in the same. This joint is by ;means of the hooks d (I, so as to conduct the snow off on the sides of the track. 7

It will be seen that the cutter a, with t-he cutters or swords E, clearaspace sufficient above and on the sides of the track 'to allow the train i to pass. The

snow thus cut passes up the incline 0, when the sword G divides it, and half is carried on each side thereof,:.uutil the wings H H throw it off on the outside of the track.

The wings H H, if too high to pass under bridges,

can be swung around and lowered, so as to come along the sides of the sword G. The wedge or sword G may extend down a suita ble distance along the center of the car 0, in which case it should be made in two pieces, hinged together at the joint between the two cars 13 and 0.

Having thus fully described my invention,

\Vhat I claimas new, and desire to secure by Letters Patent, is

1. The arrangement upon the inc-line O of the central wedge-shaped sword G, with the two wings H H hinged to its rear, and connected by the rods and books (I d, all snbstantiallyas set forth.

2. The combination of the trucks A-D, car B, incline O, with cutter a, angular cutter I sword G, and wings H. H,.all substantially as and for the purposes set forth.

In testimony that I' claim the foregoing, l have hereunto set my hand and seal this 19th day of Jan uary, 1870.
